Rhodium(I)-catalysed isomerization of cyclobutane cage compounds: synthesis of cis,syn,cis-tricyclo[5,3,0,02,6]deca-4,8-diene-3,10-dione and of exo-dicyclopentadienone
Abstract
cis,syn,cis-Tricyclo[5,3,0,02,6]deca-4,8-diene-3,10-dione has been synthesized and shown to rearrange photochemically to exo-dicyclopentadienone.
